Erythromma lindenii (Blue-eye/Goblet-marked Damselfly)

We were captivated by the mating behaviour of some of these when we first encountered them at Lac de Lenclas, southern France, in spring 2011. Pairs were landing on a stem and descending. When the female was mostly submerged, the male would leave. The female continued downwards completely submerging and eventually disappearing from sight in relatively clear water. It made me wonder if she survived the experience.
